### You will spend eternity here

The devil meets him at the gate and says, "Alright, you have died and come to hell. You will spend eternity here, but you get to choose how to spend it. You may choose one of these three doorways. Once you choose a door, you may not change it. So let's get started."

The devil opens Door One. The guy looks in and sees a couple of people standing on their heads on a Concrete floor. The guy says, "No way, let's move on."

The devil opens Door Two. The guy sees a few more people standing on their heads on a Wood floor. The guy says, "No way, let's move on."

The devil opens Door Three. The guy sees a bunch of people standing knee-deep in cow manure drinking coffee. The guy says, "Great, this is the one I will chose." The devil says, "OK, wait right here, I will get you some coffee."

The guy settles in with his coffee thinking that this isn't so bad. What's the big deal?

After about 10 minutes a voice comes over the loud speaker saying, "Coffee break's over. Back on your heads!"

### John Michell

Died 21 Apr 1793 (born 1724). British geologist and astronomer who was first to devise a realistic estimate of the distance to the stars, discovered physical double stars, and is considered the father of seismology. After the Lisbon earthquake of 1755 (which killed 70,000 people), he suggested that earthquakes set up wave motion in the earth. He noted the increased frequency of earthquakes in volcanic areas. Michell realized that by comparing the time at which earthquakes are felt, the epicentre could be calculated. He invented a torsion balance, a device to measure very small forces, though died before carrying out its purpose to determine the density of the Earth. His rebuilt apparatus was used by Cavendish to make that measurement, which also gives the gravitational constant).«[Image: Michell torsion balance as used by Cavendish]
